Hi Luis,
I agree with you that going with classes is a better way and I will =
ultimately do that as I get deeper and deeper into this.=20
I have another question regarding functions and the Execute() function =
in a class.
In my previous example, if I had wanted to return an image pointer of =
the same type as one of the inputs, is there a way to do it? The only =
way I can think of is to pass a imagetype pointer (with space allocated) =
to the function and copying the result into it in my function. Is there =
a better way to do this?
Even if I were to write it using classes, and I want my Execute() method =
to finally produce an image type, how do I return this?
How is this done with GetOutput() member functions for the various =
filters?
Thanks
Radhika
